What about a router with 3 interfaces, 2 connected to different internal 
segments and one connected to an external Ethernet.  I can imagine the 
interface group for that entity would contain three "rows".  Through
ifType, I could tell the external interface from the internal interfaces
(that reminds me, what value of ifType do we give the internal interfaces?
other(1) ?), but I don't know how to distinguish which interface is connected 
to which segment.

It seems chasConfigIfIndex solves this problem.  Or have I missed something?
